Not Becoming Friends: Situated Categorization Processes in Child-Robot Interaction

Antonia Lina; id_orcid 0009-0003-7297-412X Krummheuer, Matthias Rehm, Zhennan Yi, Nicoleta Diana; id_orcid 0009-0003-7297-412X Radu et autres

As robots increasingly enter children’s everyday environments, understanding how children categorize and relate to these technologies is central to Human–Robot Interaction (HRI). While traditional HRI approaches often treat social categorization as a cognitive construct assessed at the individual level, this paper shifts …

Building Friendships Across Borders: The Role of Social Robot Haru in Children Group Communication and Connection Development

Zhennan Yi, Leigh Levinson, Diego Delgado-Chaves, José Manuel Pérez-Molerón et autres

Forming friendship with peers from diverse backgrounds is key to children’s social emotional development. In this study, we explored the use of social robot, Haru, as mediator for remote communication in children group, to support connection and friendship building. We invited children …

En todas partes todo el tiempo: cuerpo, espacio y virtualidad

David Calero, Laura Molano, Sofía Plaza

Tras la llegada de la pandemia, el Gobierno Nacional de Colombia emitió una serie de leyes que limitaron nuestra interacción física con el otro, obligándonos a permanecer encerrados en un espacio específico para evitar conglomeraciones, a lo que le llamaron aislamiento preventivo …

A Technology-agnostic GNSS/INS Real-time Sensor Fusion Platform with Ultra Wide Band Cooperative Distance Measurements for Terrestrial Vehicle Navigation

Javier Arribas, Mònica Navarro, Ana Moragrega, David Calero et autres

This paper presents an enhancement of the well-known GNSS/INS sensor fusion approach by supporting cooperative distance measurements to improve its positioning performance for terrestrial vehicle navigation. The areas of improvement are those where the GNSS signals are severely degraded and the low-cost …

CSAC Characterization and Its Impact on GNSS Clock Augmentation Performance

Enric Fernández, David Calero, M. E. Parés

Chip Scale Atomic Clocks (CSAC) are recently-developed electronic instruments that, when used together with a Global Navigation Satellite Systems (GNSS) receiver, help improve the performance of GNSS navigation solutions in certain conditions (i.e., low satellite visibility). Current GNSS receivers include a Temperature …

Positioning performance of chip-scale atomic clock GNSS augmentation systems

David Calero, Enric Fernández, M. E. Parés

Current GNSS (Global Navigation Satellite System) receivers include an internal quartz oscillator, such as TCXO (Temperature Compensated Crystal Oscillator) or similar, limited by its frequency stability and a poor accuracy, being one of the main sources of uncertainty in the navigation solution …

Enric Fernández, David Calero, M. Eul�lia Par�s

Current GNSS (Global Navigation Satellite System) receivers include an internal quartz oscillator (or similar) limited by the frequency stability and a poor accuracy, being one of the main sources of uncertainty in the navigation solution (also multipath and ionosphere effects are an …

COMPOSICIÓN Y ESTRUCTURA TRÓFICA DE LOS MACROINVERTEBRADOS TERRESTRES DE LA ISLA MALPELO, PACÍFICO COLOMBIANO

David Calero, Mateo López Victoria, Patricia Chacón de Ulloa

Oceanic islands have special ecosystem dynamics due to their isolation and weather conditions influenced by the sea. This is also the case for Malpelo Island, located at the Colombian Pacific, where previous studies showed an invertebrate composition strongly dominated by predatory species. …
